Examples with TInterface org.eclipse.n4js.ts.types.TInterface used on opensource projects

Example 1 with TInterface

use of org.eclipse.n4js.ts.types.TInterface in project n4js by eclipse.

the class N4JSMemberRedefinitionValidator method messageImpossibleExtendsImplements.

private void messageImpossibleExtendsImplements(N4ClassifierDefinition n4ClassifierDefinition, Map<ParameterizedTypeRef, MemberList<TMember>> nonAccessibleAbstractMembersBySuperTypeRef) {
    for (Entry<ParameterizedTypeRef, MemberList<TMember>> entry : nonAccessibleAbstractMembersBySuperTypeRef.entrySet()) {
        final ParameterizedTypeRef superTypeRef = entry.getKey();
        final Type type = superTypeRef.getDeclaredType();
        final String mode = type instanceof TInterface && !(n4ClassifierDefinition instanceof N4InterfaceDeclaration) ? "implement" : "extend";
        final String message = getMessageForCLF_NON_ACCESSIBLE_ABSTRACT_MEMBERS(mode, validatorMessageHelper.description(type), validatorMessageHelper.descriptions(entry.getValue()));
        addIssue(message, superTypeRef.eContainer(), superTypeRef.eContainingFeature(), CLF_NON_ACCESSIBLE_ABSTRACT_MEMBERS);
    }
}

Example 2 with TInterface

use of org.eclipse.n4js.ts.types.TInterface in project n4js by eclipse.

the class N4JSSyntaxValidator method checkClassDefinition.

/**
 * Checks that no "with" is used and that list of implemented interfaces is separated with commas and not with
 * keywords. These checks (with some warnings created instead of errors) should help the transition from roles to
 * interfaces. However, they may be useful later on as well, e.g., if an interface is manually refactored into a
 * class or vice versa.
 * <p>
 * Note that "with" is used in Dart for roles, so maybe it is useful to have a user-friendly message instead of a
 * parser error.
